BUMPING rosr.

Application filed March Q, i322. Serial No. `540i/03.

To cli lwhom t may conca/ml f Be it known that l, Eroi-IARD l). GALLAGHER, a citizen of the United States, residing at Chicagoy in the county of Cook and State ot' illinois, have invented certain new and use-y ;iul Improvements in lumping Posts, oig

which the `following' is a specification.

My invention relates to railway bumping posts, and particularly to a form of construction thereoiwhereby the shocks ol" thereof formed of metal with the supports made of railroad rails suchias rails and bent into substantially U shape, and with the bumping block made of rcast metal and provided with recesses for receiving portions of the supports for maintaining the block in proper position at all times.

A further object is' to improve bumping post construction for generally successful commercial use, and to provide a post which may be. readily manufactured, shipped and erected.

The above recited and other objects of the invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

In the drawings:

Figure l is a side elevational view of the preferred form oi my invention.

Figure 2 is a top plan view of Figure l, and

Figure 3 is a View, partially in section, taken on line 3--3 of Figure 2.

To track rails 5 and 6 are secured the supn ports of the bumper of my invention. The bumping post comprises a bumping block T of cast metal and substantially box like in form. The block has a :flat end surface 8 against which the car couplers strike as is the usual practice. The supports ol' my invention are two in number, each formed oi' preferably T-rails and each being continuous from end to end. Referring to the drawings, the supports as may be observed, are

each ybent into substantially il `shape and i 'elevation `are curved as may be observed in igure l; while in plan, the centralk portions re straight, as will be seen in Figure 2. `he ends or" eeen of the rails forming the suiports are straight as at 9 andare provided with bolt holes l0 through which bolts ll maybe passed for securing the bumping post to the track rails and 6. ln plan each rail support is bent inwardly forming inclined portions l2 and with thecentral portions straight as at 13. Each support is like the other, and both are t'ornied in the same manner and are interchangeable. ln elevation the central part. 13 which in plan is shown ask straight is curved as at le in Figure l, and is provided with bolt holes l5. The bumping block 7 is preferably hollow for the purpose orf economy in manufacture, suitably reinflo'rced by strengthening ribs such as 16 and has formed in its sides recesses or grooves l? `Twhich are curved and shaped eK- actly to` correspond to the central portions olf the supporting members which in the present instance, are T-rails; that is, the cross section ot the recess in the block is that of a T-rail as may be observed in Figure Bolts 18 are passed through the apertures l5 in the supports `and registering apertures in the block .7 for fastening the various parts together.

The construction of the. supports and the recessed engagement of the saine with the bumping block is of such a nature and kind that when a buniping shock is imparted to the block, the shock will be imparted to the supports through the recessed engagement of the same with the block, thus relieving the bolts i8 from any strains whats ever. The curvature in elevation of the recesses in the side of the block is non-circular'. tor the pur pose of preventing the block sliding backwards under bumping impact. Non-slippage of the block is also maintained by providing an irreglfllar cross-sectional engagenient oit the supports with the block. lt will be observed that the line ot impact against the face S of the block is below the top of the central curve 14 of the side supports, which is another' reason why the block would not slide over backwards under impact.

in order to prevent shearing or 'the bolts ll which fasten the supports to the track i-IL rails 'and 6,'and in orderto maintain track alignment, l provide brace bolts 19 arranged as shown in Figure 2, that is, with one at each end ofthe bumping post which ,bolts have shoulders 2O to bear against the inner side of the webs of the supports so that" when bumping shocks are imparted to .thev

block the brace bolts i9 will opposev contraction of the supports where thesame are fastened to the track rail, thus maintaining Qtrack alignment and preventing breakageof the track bolts.

' `lt wllbe observed that a `bumping post` y cost. The only work necessary to be done is more, by .making each of the supports of a 'sor single` continuous rail added strength is secured in the structure and separation of parts is prevented. By reason of the recessed eng 'agement between the block and the supports the bumping strains arey removed from the bolts which hold the bump-l ing block in position on the supports, thereby y prolonging the life of the bumping post. y

While l have described more or less pre-v cisely the detailsv off construction of my invention l do not wish to be understood as limiting myself thereto as if'contemplateA changes in` form and proportion of parts and the substitution of equivalents as cir `cumstances may suggest or render expedient Without departing from the spirit of my invention.

I claim: y y' i n l. A bumping post, comprising in com- ;ination, a cast metal hollow block having a bumping face at one end, and supports therefor, said supports being Jformed oi' T- rails bent into substantially inverted U shape in plan and elevation, and with the ends ofsaid supports straight and bolted to the` track rails along the insides thereof, said block being formed with recesses in its sides whichy conform to the cross-section of the supports as well as to the centrally bent portion thereof; the block being mounted on said supports with the supports lying within the recesses inthe block. y

2. A. bumping post comprising` a block and symmetrical supports therefor, said block being mounted on said supportslby recessses formed in the sides of the block through which said supports pass in noncircular manner, said recesses and a portion of the supports within the same beingcurved in side elevation in such a manner that shocks received by said blocks may betransmitted directly to said supports"without displacement oi said block thereon.

3. A bumping post comprising a block o'l cast, metal and supports therefor, said blork being mounted von said supports by recesses formed in the sidesof the block, .said re,- cesses being curved in'elevation iny a noncircular path to correspond to the curvature of said supports and shaped in section to correspond to the section 4oi said supports, bolts passing throughthe supports and the block, said supports being arranged insuch a Vmanner that blows against said block may be transmitted to said supports. solely through the recessed renga-gement therewith. thereby relieving said bolts of shearing strain. f
